Maths this week

This week in maths, we have been learning about measurements on angles using a protractor. There was a little game that we had to play that was about measuring, which used an protractor. Once we think that the game has given us an idea on how it works, we had to solve angle problems which were set on a doc. During the time you get to find out what acute angles, right angles, obtuse angles, Straight angles and reflex angles are. They all have there own degree measurements, e.g right angles measure 90 degrees.

One problem has it, that there is a straight angle line (180 degree) horizontal, which has a another line sticking out form the middle, pointing 78 degrees. I have to see what the missing measurement on the other side of the line is. How I solve this is to see what number would be to make 180 degrees. (180 - 78 = 102) I think the answer would be.
